I would suggest that old PowerMac's might be the most
likely usage context.

I no longer have a PowerPC context of any kind. I mostly
booted from SATA SSD's back when I had access to working
PowerMacs. I've not been able to remember if I'd tried
FireWire based booting of FreeBSD or what the status was
if/when I did.

I did use the cross machine FireWire means of looking
into boot crashes, as it could report some console
output even after the display quit updating for some
problems I had. (I never had a serial console context
on any of the old PowerMacs.) I do not remember much
detail about this use.

I'm not sure if I can submit to freebsd-ppc any more but
I'll try for this reply. If it does not show up, you may
need to send your own message there if you want a message
about the issue there.
